IV. DETAILED DESCRIPTION OF THE INVENTION

Now referring generally to FIGS. 1 through 9, which illustrate a container opening support system (1) including apparatus and methods of making and using such apparatus which can be used to support an open end (2) of a flexible container (3) in an open condition (4) to facilitate filling the interior of the flexible container (3) with one or more containable materials (5). Embodiments of the apparatus can include an annular member (6) having an annular member perimeter (7) which can be perimetrically adjusted between a contracted condition (8)(as shown in the example of FIG. 3) insertable within an open end (2) of the flexible container (3) toward an expanded condition (9) (as shown in the example of FIG. 4) which can sufficiently tension or apply outwardly directed forces to the internal surface (10) of the flexible container (3) to support and maintain the open end (2) in the open condition (4)(as shown in the example of FIG. 1). While embodiments of the flexible container (3) are depicted as having an open end (2) opposite a closed end (11); this is not intended to preclude use of the of the container support opening system (1) with any flexible tubular membrane having at least one open end (2) engageable with the annular member (6), such as a tubular flexible membrane having a first open end (2) opposite a second open end (2).

Again, referring generally to FIGS. 1 through 9, the container opening support system (1) can, but need not necessarily, further include a handle (12) coupled to the annular member (6). The handle (12) can be gripped by a user (13) to move the opening support (1) from location to location or to position the open end (2) of a flexible container (3) in relation to containable materials (5). The containable materials (5) can be transferred into the interior of the flexible container (3) while the annular member (6) supports and maintains the open end (2) in the flexible container (3) in the open condition (4). While the illustrative example of FIG. 1 depicts containable materials (5) as being elongate rectangular objects, this is not intended to preclude any of a wide variety of containable materials (5) which can be transferred to the flexible container (3), such as: detritus, debris, waste, refuse, rubble, sweepings, trash, dirt, leaves, grass, or the like. In particular embodiments, a user (13) can grip the handle (12) of the opening support (1) with only a first hand (14) to position the open end (2) of the flexible container (3), thereby leaving a second hand (15) free to transfer the containable materials (5) into the interior of the flexible container (3). Upon receipt of the containable materials (5) within the interior of the flexible container (3), the annular member perimeter (7) can be perimetrically adjusted toward the contracted condition (8), thereby relieving the tension or decreasing the outwardly directed forces applied to the open end (2) allowing the opening support (1) to be disengaged from the flexible container (3). Subsequently, the open end (2) flexible container (3) can be disposed in a closed condition to enclose the containable materials (5) within the flexible container (3).

Now referring primarily to FIGS. 2 through 9, particular embodiments of the annular member (6) can include a first segment (17). The first segment (17) can include a first segment medial portion (18) disposed between a pair of first segment tubular end portions (19). The pair of first segment tubular end portions (19) can, but need not necessarily, be disposed generally orthogonal to the first segment medial portion (18). Each of the pair of first segment tubular end portions (19) can terminate in a first segment tubular end (20). Each of the pair of first segment tubular end portions (19) can have a tubular wall (21) having a tubular wall interior and exterior surface (22)(23). The tubular wall interior surface (22) defines a first segment tubular end portion interior space (24).

Again, referring primarily to FIGS. 2 through 9, particular embodiments of the annular member (6) can include a second segment (25). The second segment (25) of the annular member (6) can include a second segment medial portion (26) disposed between a pair of second segment end portions (27). The pair of second segment end portions (27) can, but need not necessarily, be disposed generally orthogonal to the second segment medial portion (26). Each of the pair of second segment end portions (27) can terminate in a second segment end (28). The pair of second segment end portions (27) can be slidably disposed inside of said pair of first segment tubular end portions (19). In particular embodiments, a length (29) of each of the pair of second segment end portions (27) can be correspondingly telescopically engaged within each of the pair of first segment tubular end portion interior spaces (24).

In particular embodiments as shown in FIGS. 2 through 9, the annular member (6) can have a generally rectangular or square configuration. The corners (30) of the rectangular annular member (6) can be rounded or arcuate. However, these illustrative examples are not intended to preclude an annular member (6) generally configured as: a semicircle, an oval, a semioval, an ellipse, a semiellipse, a triangle, a polygon, a freeform shape, or the like, or combinations thereof, depending upon the embodiment and the application.

Again, referring primarily to FIGS. 3 and 4, the annular member (6) can have an annular member perimeter (7) bounding an annular member interior space (31). The annular member perimeter (7) can be adjusted by sliding engagement of the pair of second segment end portions inside of the pair of first segment end portions between a contracted condition (8) in which the annular member perimeter (7) bounds a lesser annular member interior space (31) (as shown in the illustrative example of FIG. 3) in relation to an expanded condition (9), in which the annular member perimeter (7) bounds a greater annular member interior space (31) (as shown in the illustrative example of FIG. 4). Correspondingly, adjustment of the annular member perimeter (7) can provide a contracted condition (8) in which the annular member perimeter (7) has a lesser perimeter length (29) (as shown in the illustrative example of FIG. 3) in relation to an expanded condition (9), in which the annular member perimeter (7) has a greater perimeter length (29) (as shown in the illustrative example of FIG. 4). The contracted condition of the annular member perimeter (7) can be achieved by increasing the length (29) of the second segment end portions (27) correspondingly telescopically engaged within each of the pair of first segment tubular end portion interior spaces (24). Likewise, the expanded condition (9) of the annular member perimeter (7) can be achieved by decreasing the length (29) of the second segment end portions (27) correspondingly telescopically engaged within each of the pair of first segment tubular end portion interior spaces (24).

Again, referring primarily to FIGS. 2 through 9, particular embodiments of the opening support (1) can, but need not necessarily, include a securement assembly (32). The securement assembly (32) can provide releasable securement of the first segment tubular end portions (19) in incremental fixed relation to the second segment end portions (27). The securement assembly (32) operates to releasably secure at least one of the pair of second segment end portions (27) in fixed relation to the pair of first segment tubular end portions (19) at selectable discrete incremental positions (33) along the second segment end portions (27), thereby providing incremental adjustment of the annular member perimeter (7) between the expanded condition (9) and the contracted condition (8) of the annular member (6). The term “fixed relation” for the purposes of this invention means that at least one of the second segment end portions (27) is substantially immovable in at least one direction within the first segment tubular end portions (19).

Now referring primarily to FIGS. 2 through 4 and 7 through 9, particular embodiments of the securement assembly (32) can include a tubular member (34) correspondingly disposed about each of the pair of first segment tubular end portions (19) proximate the first segment tubular ends (20). The tubular member (34) can further include a biasing portion (35) terminating in a pawl (36) biased toward a first position (37) adjacent and traversing a distance across the first segment tubular end portion interior space (24) (as shown in the example of FIG. 8 in solid object line). The biasing portion (35) can be resiliently deformable to allow the pawl (36) to move toward a second position (38) in which the entirety or a lesser part of the pawl (36) traverses across the first segment tubular end portion interior space (24) (as shown in the example of FIG. 8 in broken object line). For purposes of this invention the term “pawl” means a movable element coupled to the tubular member adapted to fall into notches or interdental spaces on one of the pair of second segment end portions.

Again, referring primarily to FIGS. 2 through 4 and 7 through 9, in particular embodiments, the biasing portion (35) can, but need not necessarily, be defined by a pair of longitudinal slots (39) communicating between the tubular member interior and exterior surfaces (40)(41). The pair of longitudinal slots (39) can be disposed in the tubular member (34) extending from a tubular member first end (42) along a portion of the length (29) of the tubular member (34) towards a tubular member second end (43). Each of the pair of longitudinal slots (39) can be disposed a distance (44) apart of about 0.5 radians (rad) to about 2.2 rad. In particular embodiments, the distance (44) can be selected from the group including: about 0.55 rad to about 0.7 rad, about 0.6 rad to about 0.8 rad, about 0.7 rad to about 0.9 rad, about 0.8 rad to about 1.0 rad, about 0.9 rad to about 1.1 rad, about 1.0 rad to about 1.2 rad, about 1.1 rad to about 1.3 rad, about 1.2 rad to about 1.4 rad, about 1.3 rad to about 1.5 rad, about 1.4 rad to about 1.6 rad, about 1.5 rad to about 1.7 rad, about 1.6 rad to about 1.8 rad, about 1.7 rad to about 1.9 rad, about 1.8 rad to about 2.0 rad, about 1.9 rad to about 2.1 rad, about 2.0 rad to about 2.15 rad, or combinations thereof. However, this illustrative example is not intended to preclude embodiments in which a portion of the wall of tubular member (34) resiliently deforms out of round to achieve movement of the pawl (36) obviating the need for one or both of the pair of longitudinal slots (39).

Now referring primarily to FIGS. 2 through 4 and 7 through 9, in particular embodiments, a force receiving member (45) can, but need not necessarily, outwardly extend from the biasing portion (35) of the tubular member (34). The force receiving member (45) can transfer applied force (46) to the biasing portion (35) of the tubular member (34) to resiliently deform the biasing portion and correspondingly move the pawl from the first position (37) to the second position (38). The force receiving member (45) can, but need not necessarily, further include a force receiving surface (47). In particular embodiments, the force receiving surface (47) can, but need not necessarily, be configured to engage the a portion of the anatomy of the hand such as the thumb or finger of a hand. The force receiving surface (47) can, but need not necessarily, include patterned surface elements disposed on or in the force receiving surface (47). Patterned surface elements can extend inward or outward of the force receiving surface (47) to provide a friction enhancing texture such as dimples, protuberances, grain, ribs, or the like, or a combination thereof The illustrative example of FIG. 9, depicting a force receiving member (45) having the force receiving surface (47) is not intended to obviate other embodiments of the force receiving member (45) and force receiving surface (47). In particular embodiments, the tubular member (34), biasing portion (35), and pawl (36), can, but need not necessarily, be one piece.

Now referring to FIGS. 2 and 6 through 9, in particular embodiments, the securement assembly (32) can further include a plurality of teeth (48). The plurality of teeth (48) can be disposed in spaced apart relation on each of the pair of second segment end portions (27). In particular embodiments, the second segment end portions (27) and plurality of teeth (48) can be fabricated or formed as one piece. In particular embodiments, the plurality of teeth (48) can, but need not necessarily, be removably fastenable to each of the second segment end portions (27).

As shown in the illustrative examples of FIGS. 2 and 8, the plurality of teeth (48) can comprise a toothed rack (49) which can be removably fastened to the second segment end portions (27) by use of mechanical fasteners, interlocking configuration, adhesives, or a combination thereof. The plurality of teeth (48) can correspondingly move with the pair of second segment end portions (27) telescopically engaged with the first segment tubular end portions (19). An intermediate space (50) can occur between each adjacent pair of the plurality of teeth (48). The intermediate space (50) can be configured to receive the pawl (36) in the undeformed condition of the biasing portion (35). The pawl (36) can be moved from the first position (37) disposed in the intermediate space (50) to the second position (38) out of the intermediate space (50) by resiliently deforming the biasing portion (35) of the tubular member (34). The removable engagement and disengagement of the pawl (36) from the intermediate space (50) can permit incremental adjustment of the annular member perimeter (7) by permitting the second segment end portions (27) and first segment tubular end portions (19) to be releasably secured in fixed relation in incremental positions (33) along the plurality of teeth (48).

Now referring primarily to FIG. 8, in particular embodiments, each of the plurality of teeth (48) include first and second tooth faces (51)(52). The first tooth face (51) of each of the plurality of teeth (48) can have a steep slope, oftentimes nearly orthogonal or orthogonal to the surface from which the tooth (48) extends (whether the second segment end portion (27) or the toothed rack (49)) while the second tooth face (52) can have a moderate or gradual slope to the surface from which the tooth (48) extends. The pawl (36) positioned in the intermediate space (50) between a pair of the plurality of teeth (48) can ride over the first tooth face (51) of a plurality teeth (48), repeatedly resiliently deforming the biasing portion (35) of the tubular member (34), allowing movement of the second segment end portions (27) in a first direction (53); however, the pawl (36) positioned in an intermediate space (50) between a pair of the plurality of teeth (48) cannot ride over the second tooth face (52), thereby preventing movement of the second segment end portions (27) in a second direction (54). Typically, the second tooth face (52), having moderate or gradual slope in relation to the surface from which it extends, allows movement of pawl (36) over the plurality of teeth (48) disposed on the pair of second segment end portions (27) without user interaction to resiliently deform the biasing portion (35) of the tubular member (34) to move the pawl (36), thereby allowing unidirectional movement of the pair of second segment end portions (27) toward an expanded condition (9) of the annular member (6), thereby allowing the annular member perimeter (7) to engage and tension the internal surface (10) of the flexible container (3) but preventing movement of the pair of second segment end portions (27) toward the contracted condition (8) of the annular member (6) except by user interaction with the biasing portion (35) of tubular member (34) to disengage the pawl (36) from the intermediate space (50) to release tensioned engagement of the annular member (6) with the internal surface (10) of the flexible container (3).

Now referring primarily to FIGS. 2 through 4, particular embodiments of the container opening support system (1) can further include a handle (12). The handle (12) can be coupled to the first segment (17) of the annular member (6). In particular embodiments, the first segment (17) and the handle (12) can, but need not necessarily, be a single piece as depicted in FIGS. 2 through 4. The handle (12) can extend from the first segment (17) into the annular member interior space (31) defined by the annular member perimeter. The handle (12) can be gripped by a user (13) to move the opening support (1) from location to location or to position the container open end (2) in relation to the containable materials (5). In other particular embodiments, the handle (12) can extend from the first segment (17) away from the annular member interior space (31). In further embodiments, the handle (12) and annular member (6) can, but need not necessarily, both be disposed in one substantially flat plane. There can be a substantial advantage in the handle (12) extending from the first segment (17) of the annular member into the annular member interior space (31) defined by the annular member perimeter (7). The distribution of the mass of the annular member (6) in relation to the handle (12) yields a shorter lever arm with less mass thereby requiring less force applied to the handle (12) to move the annular member (6).

Now referring primarily to FIGS. 3 and 4, in particular embodiments, a tack layer (55) can be directly or indirectly coupled to the annular member (6). In particular embodiments, the annular member (6) and tack layer (55) can, but need not necessarily, be one piece. In particular embodiments, the tack layer (55) can be disposed as a discrete layer overlaying, applied to, or sprayed upon the annular member perimeter (7). The tack layer (55) affords a surface having a sufficiently high coefficient of kinetic friction or static friction, or combinations thereof, to oppose movement of the internal surface (10) of the open end (2) of the flexible container (3) during normal use. For the purposes of this invention, the term “tacky” generally refers to a property of a material to adhere to or resist movement in relation to another material. The tack layer (55) can be disposed over all or a portion of the first segment external surface (56), all or a portion of the second segment external surface (57), all or a portion of both the first and second segment external surface (56)(57), or combinations thereof In particular embodiments, the tack layer (55) can be a different material than the material of the annular member (6). The tack layer (55) can be a material having a greater static coefficient of friction, kinetic coefficient of friction, or both, than the annular member. The tack layer (55) can be selected from the group including a wide variety of tacky polymeric resins, such as: polyurethane, silicone, epoxy, acrylics, polyesters, melamine resins, or combinations thereof.

Now referring generally to FIGS. 1 through 9, particular methods of using embodiments of an opening support (1) can include sliding a pair of first segment tubular end portions (19) over a pair of second segment end portions (27) and biasing a pawl (36) coupled to each of the first segment tubular end portions (19) against a plurality of teeth (48) disposed in spaced apart relation on each of the pair of second segment end portions (27) to fix the position of the first segment (17) in relation to the second segment (25). The method can further include resiliently deforming the biasing portion (35) of each of a pair of tubular members (34) coupled to each of the first segment tubular end portions (19) to disengage the pawl (36) from the plurality of teeth (48) disposed on the corresponding second segment end portions (27). The methods can, but need not necessarily include inserting the annular member (6) inside an open end (2) of a flexible container (3). The methods can further include, adjusting the annular member (6) between a contracted condition (8) bounding a lesser annular member interior space (31) toward an expanded condition (9) bounding a greater annular member interior space (31), the expanded condition (9) engaging an annular member perimeter (7) with an internal surface (10) of the open end of the flexible container (3).

The method can further include engaging a tack layer (55) coupled to the annular member perimeter (7) with said internal surface (10) of the open end of the flexible container (3).

Components of the container opening support system (1), including the annular member (6), can be made by any of a numerous and wide variety of processes, depending upon the application. As non-limiting examples, the process can include press molding, injection molding, fabrication, machining, printing, additive printing, or the like, or combinations thereof.

Regarding materials, components of the container opening support system (1), including the annular member (6), can be made from any of a numerous and wide variety of materials, depending upon the application. As non-limiting examples, the material can include metal, wood, plastic, plastic-like material, rubber, rubber-like material, injection-moldable material, or the like, or combinations thereof. By way of non-limiting example, the annular member (6) can be a polymer selected from the group including or consisting of: nylon, polyethylene, polypropylene, polycarbonate, acrylonitrile butadiene styrene, or the like, or combinations thereof. As to particular embodiments, additives such as glass fibers, ultraviolet absorbing materials such as cerium oxide, titanium oxide, or zinc oxide, or combinations thereof.

As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of a container opening support system and methods for making and using such a container opening support system including the best mode.

As such, the particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.

It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which that physical element facilitates. As but one example, the disclosure of a “biasing portion” should be understood to encompass disclosure of the act of “biasing a portion”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “biasing a portion”, such a disclosure should be understood to encompass disclosure of a “biasing portion” and even a “means for biasing.” Such alternative terms for each element or step are to be understood to be explicitly included in the description.

In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to be included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.

All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. When a value is expressed as an approximation by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result. Similarly, the antecedent “substantially” means largely, but not wholly, the same form, manner or degree and the particular element will have a range of configurations as a person of ordinary skill in the art would consider as having the same function or result. When a particular element is expressed as an approximation by use of the antecedent “substantially,” it will be understood that the particular element forms another embodiment.

Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity unless otherwise limited. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.

Thus, the applicant(s) should be understood to claim at least: i) each of the container opening support systems herein disclosed and described, ii) the related methods disclosed and described, iii) similar, equivalent, and even implicit variations of each of these devices and methods, iv) those alternative embodiments which accomplish each of the functions shown, disclosed, or described, v) those alternative designs and methods which accomplish each of the functions shown as are implicit to accomplish that which is disclosed and described, vi) each feature, component, and step shown as separate and independent inventions, vii) the applications enhanced by the various systems or components disclosed, viii) the resulting products produced by such systems or components, ix) methods and apparatuses substantially as described hereinbefore and with reference to any of the accompanying examples, x) the various combinations and permutations of each of the previous elements disclosed.
